Dolphin Integration promotes a design methodology ensuring High-Yield circuits despite Mismatch

Meylan, France – December 4th, 2009. As the promoter of innovative Virtual Components of Silicon IP and methodologies for the Microelectronics Design Industry, Dolphin Integration takes the responsibility of setting up a method enabling the assessment of design yield for any memory generator.

Traditional simulations based on worst-case corners (process, temperature, voltage) do not allow measuring the negative impact of the performance variations of transistors due to the dispersion between transistors on the same circuit.

To take into consideration such Mismatch effects, Monte Carlo simulations are required, resulting in a huge amount of computer time. For a memory generator, simplifications of models are necessary, but must result in a safe design. In any case, what is missing is a standard method for assessing the design yield of a memory during simulation and specifications based on clear acceptance criteria.

Design yield can only be guaranteed by a combination of worst-case corners simulation and mismatch simulation. The embedded Memory Provider has built a two steps methodology to take into account the offset for the design and the validation of any memory generator, with the objective of achieving high design yield while maintaining optimized performances. The Dolphin method enables both an a-posteriori verification of mismatch and an a-priori implementation during the memory design.

SoC designers can benefit from both Dolphin Integration’s design methodology and an overall catalog of Static RAM and Via-Programmable ROM satisfying the expectations of most of consumer and industrial applications.
